f My invention relates toimprovements in4 -doors for grain cars in which it 1s sought to.'

'provide an eeonomical'fan'tl reusable fdoor,

Similar numerals refer to similar parts throughout the several views. 'The device consists of a east member supporting a bolt, formed to detachably engage with one gamb of a doorway, which cast vmember supports one end of a plank transverse the Idoor opening, the other end 'of the lplanlrbeing supported by the door jamb opposite the cast member. The plank 2, is held in position by the outward thrust oflthe grain in the conveyance.

The casting `l, in the preferred embodi ment of my invention is of angular cross section, having formed inthe internal'an.-v gie, and integrally with the main casting,

sleeve 3. The said'sleeve has frontal, eX- ternal orifices or ports fornth'e vpurpose hereinafter mentioned. Slidably engaged in the said sleeve is the locking bolt G, having yif) recessed notches in saine at `7 and 8 suitably disposed to bear a definite relationshipito ythe ports 4t and 5 in the sleeve 3. The lower portion of the (bolt member 6,1s formed to circular crosssection to enter into a socket l0 cut in the sill' of the doorway. The face of the bolt member 6, opposite to the notches '.7 and 8, Acontains a groove" l1, terminated short of the upper ancllower ends'of the bolt. The threaded screw 12 passesA through i the wall of the main 'casting into the groove Y ll, referred to, and prevents the bolt member from dropping out of its sleeve when the device is not in use. Y l

The main casting l, is finished at its upper end into a lug 13, extended as shown lto provide anfengagement with a socket 14',

- Veut in the yinterior `wall ofthe conveyance',

adjacent to the doorway. AThis forms a simple pivotal bearing for therotation of vchanieal parte.y

The mainl casting" l,v `rib 16, on 'the fa'ce,Y presented tov the interior tof "the V'co'11",'Yeyance, i to prevent travel "en-df ways ofthe plank 2... 'The opposite `end of has falso/a 'vertical plank 2 to that'engagedfwith the casting passes beyond the `door-.opening and bears`v lthe lug lfbeing'entered into thesocket le,

and the bolt member 6v being thrust down into the sill socket 10'.k The plank 2 is thenv l placed in posit-ion and isheld there bythe e,

outward thrust of the grain deposited behind same. To discharge the grain a y@row so.y

bar isinsert-edfinto-ports 5 and e, and 'byj engagement Withthe notches ,7 and;8,the

bolt .memberisrased clear of thejs'ill socket i its pivotal,bearingA 13, allowing the plank to be removed."

The' outward .pressure 'of the grainl forces the .casting l, to swing outwards lonv .I am vaware thatl prior to my invention grain doors have been made,wherein a plank,"l

or .barrier has `been adjustably restrained againstlthe outward thrust of thegrain," and released bythe disengagement of mel therefore do not claim such a combination broadly, but- Vhat I claim is:y

l. The combination with a doorway', of an angular casting abutting the face ofthe Vdoor y jamb, an-'extension lug formed thereon engaging in a rsocket inthe interior wall. sur- -face adgacent tothe doorway, a vertical sleeve in thesaid casting, a bolt'slidably supported in the said sleeve adaptedA to engage in a 'socket inthe sill of theeldoorway, means forfactuating the bolt to: engagement or disengagement ywith the sill, means limiting the travel of the bolt in th'esleeve,fa bar,-

rier o member across the doorway supported by the casting at one end and .the oppo-v site doorL jamb` at,v the 'otl1er.`end-,meansy preventingv lateralv motion of the barrier ginem'ber;

2;5The combinationy with a doorway,of

angular casting abutting the face of the door jamb, an extension lug formed thereon engaging in a socket in the interior wall surface adjacent to the doorway, a vertical sleeve in the said casting, ports in the Said sleeve, a bolt Slidably supported in the sleeve adapted to engage in a socket in the sill of the doorway, notches on the face of the bolt exposed through the ports inl the sleeve, means limiting the travel of the bolt in the sleeve, a barrier member across the vdoorway supported by the casting at one end and by the opposite door jamb at the other end, means preventing lateral motion of the barrier member. l

3. The combination with a doorway, of an angular casting abutting the face of the door jamb, an extension lug formed thereon engaging in a socket in the interior Wall Surface adjacent to the doorway, a vertical rib on the casting projecting on the interior face, a vertical sleeve in the saidcasting, ports in the said Sleeve, a bolt slidably supported in the sleeveadapted to engage in a socket in the sill of the doorway, notches on the face of the bolt exposed through the ports in the sleeve, means limiting the travel or' the bolt in thel sleeve, a barrier member across the'doorway supported by the cast-ing at one end and by the opposite door jamb at the other end, a projecting rib formed on the exterior face of the barrier member engaging with that door jamb opposite to the casting all Substantially as specied and for the purpose set forth.
